What you'll learn

The definition and the purpose of lock out & tag out (LOTO) in any process industries

The steps and methods of achieving safety from the system to be worked on

The sequence of isolation and normalization of equipment in process industires

Practical means for achieving safety from the system to be worked on

Roles and responsibilities of the personnel involved in LOTO

General rules to be followed in achieving safety from the system

Description

Chapter-1 gives an introduction of the session on lock and tag out. In chapter-2, I have explained where exactly the lockout and tag out falls in the hierarchy of safety controls. Also I explained about the purpose of lock and tag out.Chapter-3 describes about the definition of lock and tag out, sequence of achieving lock and tag out, some of the hazards that are prevailing in industries.In chapter-4, the contents of an isolation tag, release of residual stored energy and typical risks due to a hazard are explained.Chapter-5 elaborates about the energy isolation process.Chapter-6 talks about the importance of sequence of isolation and normalisation and few sequence of isolation commonly followed in industriesChapter-7 illustrates about some more sequence of isolation used in industries.Chapter-8, explains about sequence of normalization, ways to confirm zero energy importance of verification of isolation, procedure for test and re- commissioning.In Chapter-9 , the practical ways and means of achieving safety from pipelines electrical isolation and procedures for bypassing safety systems are explainedIn chapter-10, some of the positive isolation devices that are used , where there is no provision of lock is there. In chapter-11, the personnel involved in lock and tag out procedures are defined with their roles and responsibilities.In chapter-12, steps involved in Energy isolation are mentioned. Also the chapter explains how to confirm safe isolation. Why lock out/ tag out fails is also mentioned.In chapter-13, some of the general rules in lock out and tag out are elaborated.Chapter-14 discusses safe removal of lockout, restoration of energy and conditions for special removal.Chapter-15 summarises the lessons learned from all sessions and adds a conclusion.
